Polish Corridor in gray; Germany in green; free city of Danzig in green with hatching
A strip of land between the German territories of Pomerania and East Prussia, awarded to Poland by the Treaty of Versailles (1919) to afford access to the Baltic Sea. After years of friction over control of the area, Germany invaded Poland (1939) and quickly captured the Polish Corridor, triggering World War II and ending the Corridor's existence as a distinct geographical entity.
